Author here, happy to answer questions about this. See the discussion a month ago at https://news.ycombinator.com/item?id=24167804 https://news.ycombinator.com/item?id=24167804 as well. Since then I'm improved the website somewhat and added some demo code to the front page: hit the arrow at the right of the REPL box to see it all. Documentation is slowly getting more complete, for example with full documentation of blocks including functions at https://mlochbaum.github.io/BQN/doc/block.html https://mlochbaum.github.io/BQN/doc/block.html. Performance is improving and there is some error checking! I've been working on a NumPy runtime as well. It passes most tests but can't host the compiler, as I haven't yet found the motivation to hack my way through the searching and sorting functions that NumPy won't help with.
